Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X900-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 900mm stroke, G1/2 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75S
The hard-anodized aluminum profile barrel keeps the overall body more compact than a same-bore ISO 15552 unit.
The -75 code means an external stop screw can shorten the 900 mm extend stroke by up to 75 mm on-site, letting you fine-tune the end position without swapping the cylinder. The retract end remains fixed. This double-acting double-rod unit features a G1/2 port, an M26x1.5 rod thread, and 33 mm adjustable air cushions at both ends. The -S suffix adds a piston magnet for CMSE/DMSE switches in the side grooves.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

| Max (@1.0 MPa) | 719 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75S Is Used
Long-Transfer Pushing
Moves heavy pallets along a 900 mm conveyor section, using the 75 mm adjuster to dial in the exact push-off distance for different product sizes.
Large Door Actuation
Opens heavy machine guarding doors, fine-tuning the closed position on-site with the external stop screw to match the door frame perfectly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75S the Right Cylinder?
The adjustable window shines when you need to dial in a precise end-of-stroke hit on-site or want a single spare cylinder to cover several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 900 mm, you must use external guides to prevent rod bending and side loads. The built-in magnet supports CMSE/DMSE sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X900-75S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore cylinder uses a G1/2 air port and an M26x1.5 rod thread.
The nominal 900 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 825 to 900 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load on air loss.
